Enzyme Information
| 2.8.1.13 |
tRNA-uridine 2-sulfurtransferase.
based on mapping to UniProt P25745
A [protein]-S-sulfanyl-L-cysteine + uridine(34) in tRNA + ATP + reduced acceptor = a [protein]-L-cysteine + 2-thiouridine(34) in tRNA + AMP + diphosphate + acceptor.
-!- The enzyme, found in bacteria, catalyzes formation of the 2-thiouridine modification in the wobble position of tRNA(Gln), tRNA(Lys) and tRNA(Glu).
